Pneumatic adjustable wrenches is famous for its small size, light weight, high output power per unit weight and you can achieve high torque output with small reaction force, less environmental pollution and low cost these advantages. This kind of adjustable wrenches is widely used in the aerospace, mining, petrochemicals, railways, construction, heavy vehicle assembly maintenance, loading and unloading of heavy equipment many fileds, especially widely used in the production assembly line, particularly the need for high torque applications.
Pneumatic adjustable wrenches is a kind of adjustable wrench with high-pressure air pump as its power source. Pneumatic adjustable wrenches is driven by one or two powerful air motor to push the torque multiplier with three or more gears turnover.Pneumatic adjustable wrenches is controlled by adjustable gas pressure.
